To participate in a clinical trial, please read the information and get in touch with the contact person directly. (Note that you can use the filters at the top of the ClinicalTrials.gov page to show only trials that currently are recruiting volunteers.)

ClinicalTrials.gov was created in response to the Food and Drug Administration Modernization Act of 1997, which requires the U.S. Department of Health and Human Services, through the NIH, to establish a registry of both federally and privately funded trials "of experimental treatments for serious or life-threatening diseases or conditions."

In 2007, the ClinicalTrials.gov database was expanded after Congress passed the Food and Drug Administration Amendments Act, which requires more types of clinical trials to be registered (such as trials for certain medical devices) and more information about clinical trials to be made available to the public.

Studies listed in the ClinicalTrials.gov database are categorized as either interventional or observational. Interventional studies are those in which the research subjects are assigned to a treatment or other intervention, and outcomes are measured. In observational studies, individuals are simply monitored and certain criteria are measured by investigators.
